Description

[0001] The present invention relates to a distributor and a valve,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coupling structure of a distributor and a valve, and more particularly, to a coupling structure of a distributor and a valve, And to a fastening structure of a distributor and a valve which are prevented from deformation of the fastening part and whose life is prolonged and which are easy to install.

Generally, a distributor is used to distribute the heating water supplied from a heating device such as a boiler to various zones where heating water is used, and a plurality of valves are connected to the distributor. In addition, the distributor is used for distribution of hot water and cold water in addition to the heating water, and distributes the fluid such as heating water, hot water, and cold water to the piping pipe to flow.

Due to the action of the distributor, the fluid such as the heating water is branched out to the respective sections through the distributor without flowing out.

A connecting port for connecting the valve to the conventional distributor is formed on the radially outer surface of the distributor, and a female thread is formed inside the connecting port. Correspondingly, a male screw portion is formed at the end of the valve facing the connection port. Thus, the connection port and the valve are coupled by a screw connection method. In order to prevent leakage through a gap in the connection portion, an epoxy resin is applied to the screw groove and the thread, and then, the epoxy resin is cured.

However, it is difficult for the distributor having such a coupling structure to perform the precise construction in the field, so that frequent contact of the distributor and the valve or the carelessness of the workers causes cracking of the epoxy hardened part, Respectively. Further, due to frequent carelessness of the operator, the control part of the valve, for example, the opening / closing handle and the actuator, which is to be positioned at the upper part, is rotated and moved to the lower part.

One end of the coupling port 20 is connected to the distributor body 11 in order to allow the fluid such as hot water, heating water, cold water, etc. to be distributed from the distributor 10 to flow to the piping pipe (not shown). That is, the coupling hole 20 communicates with the first central opening 12 of the distributor body 11 through the upper end. A valve (30) is inserted into the open end of the coupling hole (20).

Fig. 3 shows the installation state of the distributor 10 and the valve 30 as described above.

Referring to FIG. 3, the distributor 10 is installed at a separate installation site where the inlet pipes and the discharge pipes of the pipes are concentrated so that the fluid such as heating water can be divided into the respective sections. At this time, And the flange 13 is fitted to the flange 13, as shown in Fig.

In addition, coupling of the coupling port 20 and the distributor body 11 so as to allow the fluid to flow may have various structures other than the above-described structure.

A coupling port expanding portion 22 is provided downstream of the coupling port inserting portion 21. The coupling hole expanding portion 22 is formed to have an inner diameter enlarged by a certain size larger than the coupling hole inserting portion 21. [ The fitting hole 21 and the fitting hole 22 extend smoothly. Preferably, the coupling port insertion portion 21 and the coupling port expanding portion 22 are formed to have a circular cross section. The coupling port lower portion 23 is connected to the downstream of the coupling port expanding portion 22. The coupling port lower portion 23 is formed to have an inner diameter enlarged by a certain size larger than the inner diameter of the coupling port expanding portion 22. [ Preferably, the lower portion 23 of the coupling port is formed to have a polygonal cross-section. For example, the lower portion 23 of the coupling hole may have a cross-sectional shape such as a square, a hexagon, or an octagon. The upper portion of the valve 30 is press-fitted into the coupling hole 20 thus formed.

The reason why the lower portion 23 of the coupling hole 23 is formed to have a polygonal cross section is that when the caulking operation is performed while the upper portion of the valve 30 is press-fitted into the coupling hole 20, So as to strengthen the fastening force, to prevent the valve from coming off, and to fix the position of the valve.

The valve 30 has a valve body 31 having a second central opening (not shown) that is distributed from the distributor 10 and serves as a passage for the fluid flowing through the coupling 20.
